Title: Separator for particulate materials
IPC: B07B1/18
Filed: 1960-05-19
Abstract: 916,081. Rotary cylindrical screens; pneumatic separators. BELL INTERCONTINENTAL CORPORATION. May 19, 1960 [Nov. 13, 1959], No. 17654/60. Class 117. In a separator, e.g. for recovering reusable blast material, material is screened by a rotating cylindrical screen and the throughs are separated by a transverse air blast while falling in a curtain of substantially uniform thickness. As shown in Fig. 1, material is fed by a conveyer 14 to a rotating cylindrical screen 15 carrying a helical feeding device 32 within it. Oversize material falls through a shoot 34 and the throughs fall into a hopper 30, Fig. 2, where they are moved lengthwise by a helical ribbon 55 mounted on the outside of the screen. To ensure that material for pneumatic separation falls in a curtain of substantially uniform thickness, flow of material from the hopper 30 is controlled by an adjustable positioned fixed gate plate 28 and by a pivoted plate 44 carrying counterweights 50. The plate 28 extends from the feed end of the hopper to a position 62, Fig. 1, short of the opposite end whereas the pivoted plate 44 extends throughout the hopper's length. The arrangement is such that, as long as material passes only beneath the fixed plate 28 to the pivoted plate 44 the weight bearing on this plate is insufficient to pivot it to its open position and flow of material over a spill plate 38 is blocked. However, as more material passes through the screen and is moved along the hopper 30 by the helical ribbon 55 it eventually flows past the end 62 of the fixed plate 28 and the added weight on the pivoted plate 44 pivots it to its open position. Material then flows uniformly over the spill-plate 38 and is subjected to an air blast from an opening 70, the coarser material falling into a shoot 78 and the finer material 79 into a hopper 80.

Abstract: 421,423. Return - tube steam boilers. PETTY, T., 43, Greta Avenue, West Hartlepool, and RICHARDSONS, WESTGART, & CO., Ltd., Hartlepool. June 24, 1933, No. 18075. [Classes 123 (ii) and 123 (iii)] In an installation of multi-furnace return-tube boilers one or more furnaces of one or more boilers instead of leading to the usual combustion chamber communicates with an external superheater chamber containing steam superheating elements through which all or most of the steam from all the boilers is passed. Or a single boiler may be similarly provided with one or more such chambers. If the number of superheater chambers required in a plant is equal to the number of furnaces in a boiler one boiler may have all its combustion chambers replaced by external superheater chambers, and hence be made of furnace length only. A ship's installation comprises three Scotch boilers each with four furnaces, and one boiler accommodates all the superheating elements 9 of the plant in two external chambers 8 connected to the centre furnaces 5 in place of the usual combustion chambers, the furnace gases passing through return flues 11 or a number of smaller tubes to the smoke box 4. Another arrangement provides superheaters for all the furnaces of one boiler the length of which corresponds to the normal furnace length. The furnaces 5 and return flues may be contained in two communicating cylindrical shells. In operation the normal furnaces are fired in accordance with the steam pressure, whilst the super. heating furnaces are controlled in dependence on superheated steam temperature. The superheater elements may consist of inverted U-tubes secured to a tube plate 14, the legs of the first two rows, which are staggered, being in line with the furnace axis and the legs of both rows nearer the furnace being traversed by wet steam or shielded by baffles from direct radiation. The legs of the other elements may be arranged to provide equilateral pitching and may be so bent or grouped as to provide a peripheral tube wall for the superheater casing. In a modification the elements are suspended from headers at the top of the casing and are of such length that their ends are wholly or partly screened from direct radiation. Or they may comprise straight tubes between forged steel headers or serpentine elements made up of U-tubes connected in series.
